Low-complexity message formats and procedures are disclosed, greatly simplifying the task of user devices in recognizing downlink messages in 5G/6G. A user device, not requiring high performance or low latency, may request a “custom search-space” in which downlink messages may be transmitted by the base station, thereby greatly reducing the calculation overhead of the user device. In addition, message formats are disclosed that may enable rapid identification of relevant messages, and rejection of other messages, without performing a “blind search” and other arduous procedures. In addition, messaging protocols are disclosed that may avoid unnecessary control signaling, thereby saving time and energy. Low-cost wireless devices may be enabled by such low-complexity options in future wireless networks.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The media of claim 1, wherein the request for a custom search-space and the downlink data message are transmitted according to 5G or 6G technology.
3. The media of claim 1, the method further comprising transmitting, to the user device, a search-space assignment message indicating at least the particular subcarrier and the particular symbol time.
4. The media of claim 1, the method further comprising transmitting, to the user device, a downlink control information message indicating that the downlink data message is to be transmitted.
5. The media of claim 4, wherein the downlink control information message is transmitted, at least in part, in the custom search-space.
6. The media of claim 4, wherein the downlink control information message indicates an identification code of the user device and a size or length of the downlink control information message.
7. The media of claim 4, wherein the downlink control information message indicates a size or length of the downlink data message.
8. The media of claim 1, wherein the downlink data message indicates an identification code of the user device.
9. The media of claim 1, wherein the downlink data message indicates a size or length of the downlink data message.
12. The media of claim 11, the method further comprising determining, according to the request for the custom search-space, whether the user device requests that an identification code of the user device be transmitted in the downlink data message.
14. The wireless transceiver of claim 13, wherein the request for the custom search-space specifies how many resource elements comprise the custom search-space.
15. The wireless transceiver of claim 13, wherein the request for the custom search-space specifies whether the base station is to transmit a downlink control information message to the user device before transmitting the downlink data message.
17. The method of claim 16, further comprising transmitting, to the user device, a downlink control information message before transmitting the downlink data message, the downlink control information message configured to indicate that the downlink data message will be transmitted thereafter.
18. The method of claim 16, further comprising transmitting, to the user device, concatenated with the downlink data message, an identification code of the user device and an indication of a size or length of the downlink data message.
